A pretty blonde comes in to a service station and asks for a seven-hundred-ten. Mechanics all look around at each other and another customer asks, "What is a seven-hundred-ten?" She replies, "You know, the little piece in the middle of the engine, I have lost it and need a new one." She says that she did not know what it was but this piece has always been there.

Manager gives her a piece of paper and a pen and asks her to draw what the piece looked like. She draws a circle and in the middle of it writes 710. He then takes her over to another car which has its hood up and asks "is there a 710 on this car?" She points and says, "Of course, it's ... right there" ... go on, click on "right there"

C'mon now; do I have to turn it upside down for you?

And we return to ... Navigator ... that's a blonde.
